Abstract

La présente invention concerne un procédé et un appareil de communication sans fil. Un équipement d'utilisateur reçoit des premières informations, reçoit ensuite des signaux sans fil d'un premier type K1, et envoie des secondes informations dans un premier intervalle de temps. Les premières informations sont une signalisation de couche élevée, et le premier intervalle de temps est l'un de L intervalles de temps. Les premières informations sont utilisées pour déterminer une position du premier intervalle de temps dans les L intervalles de temps, et les secondes informations sont utilisées pour déterminer si les signaux sans fil du premier type K1 sont correctement décodés. Via la conception de premières informations, la présente invention prend en charge l'envoi d'informations d'accusé de réception de requête automatique de répétition hybride (HARQ-ACK) correspondant à des signaux sans fil d'un premier type K1 dans le premier intervalle de temps. En cela, l'invention optimise la transmission d'informations de commande de liaison montante (UCI) pour un HARQ-ACK, réduit les surdébits de ressources et de puissance de transmission d'informations de commande de liaison montante, et améliore les performances globales du système ainsi que le rendement spectral.
